A step-down circuit is connected to an output of a step-up circuit that steps up a battery voltage, and an output of the step-down circuit is connected to a power supply input terminal of a CPU via an FET. The step-down circuit is normally maintained in an inactive state and, in response to an ignition switch being turned off, the CPU causes the step-down circuit to actuate and a stepped-down voltage (equal to a stabilized voltage) is output from the step-down circuit. The stepped-down voltage is further stepped down to a CPU power supply voltage, and the CPU power supply voltage is supplied to the power supply input terminal of the CPU. This allows the residual charge of the step-up circuit to be dissipated by the step-down circuit and the CPU.

Fuel injection device of internal combustion engine

A connector includes: a terminal fitting having a body portion; and a housing having a cavity that receives the terminal fitting, wherein the body portion has a first protrusion that protrudes from an outer surface of the body portion and an interference avoiding portion, wherein the first protrusion and the interference avoiding portion are disposed to be opposed to each other substantially in a diagonal line on a virtual projection plane, and wherein the cavity is formed with, in an inner surface thereof, a first groove into which the first protrusion is allowed to enter only when the terminal fitting has a proper insertion posture relative to the cavity and an interference portion that is formed to swell from the inner surface of the cavity to narrow a gap with the interference avoiding portion.

Electrical connector with terminal orientation features

A terminal fitting includes: a body portion having a space for inserting a tab of a mating terminal therein; an elastic contact piece provided to face the space, having a configuration as to be extended like a cantilever in a direction of an insertion and pull-out of the tab with respect to the space through a wall-shaped portion constituting the body portion, and having a contact portion to come in contact with the tab; and an elastic reinforcing piece provided on an opposite side to the space with the elastic contact piece interposed therebetween, having a configuration as to be extended like a cantilever in the direction of the insertion and pull-out of the tab from the wall-shaped portion constituting the body portion, and causing an extended end to correspond to a displaced region in an elastic flexure in the elastic contact piece.
